Solve<br> -21 = -9 + 2/3b

Svet_ta [14]

Final Answer: $b = -18$

Steps/Reasons/Explanation:

Question: Solve $-21 = -9 + \frac{2}{3}b$ .

<u>Step 1</u>: Simplify $\frac{2}{3}b$ to $\frac{2b}{3}$ .

$-21 = -9 + \frac{2b}{3}$

<u>Step 2</u>: Regroup terms.

$-21 = \frac{2b}{3} - 9$

<u>Step 3</u>: Add $9$ to both sides.

$-21 + 9 = \frac{2b}{3}$

<u>Step 4</u>: Simplify $-21 + 9$ to $-12$ .

$-12 = \frac{2b}{3}$

<u>Step 5</u>: Multiply both sides by $3$ .

$-12$ × $3 = 2b$

<u>Step 6</u>: Simplify $-12$ × $3$ to $-36$ .

$-36 = 2b$

<u>Step 7</u>: Divide both sides by $2$ .

$-\frac{36}{2} = b$

<u>Step 8</u>: Simplify $-\frac{36}{2}$ to $-18$ .

$-18 = b$

<u>Step 9</u>: Switch sides.

$b = -18$

A cuboid has side lengths 3cm, 4cm and 7cm. A cylinder with a height double that of the longest side of the cuboid has the same

mart [117]

Step-by-step explanation:

Longest side of cuboid: 7cm

Height of cylinder:

2 × 7 = 14 cm

Volume of cuboid:

7x3x4=84 $cm^3$

Volume of cylinder:

$84=14\pi r^2 \\r=\sqrt{\frac{6}{\pi} } \ \ \ cm\\r=1.38 \ cm\\$

Surface area of the cylinder:

$\pi r^2 + 2 \pi r h$

$6+2\pi (\sqrt{\frac{6}{\pi} } ) (14)$

=128 cm^2
